Add configurable Max Retry Count setting for sync jobs in Airbyte Cloud UI

[syedkhadeer-cmd]

Problem: Airbyte Cloud users cannot configure the maximum number of retry attempts for sync jobs. Currently, when a sync fails, Airbyte Cloud may retry up to 15-20 times before marking the job as failed. This behavior is not configurable through the UI.In contrast, Airbyte OSS/Self-Managed deployments allow operators to configure this via environment variables like SYNC_JOB_MAX_ATTEMPTS, SYNC_JOB_RETRIES_COMPLETE_FAILURES_MAX_SUCCESSIVE, and SYNC_JOB_RETRIES_COMPLETE_FAILURES_MAX_TOTAL.

**Use Case:**Customers want to limit sync retry attempts to a smaller number (e.g., 3) to:Fail fast and receive notifications sooner when there are persistent issuesReduce unnecessary resource consumption from repeated failed attemptsAlign with their operational workflows and alerting thresholds.

**Proposed Solution:**Add a "Max Retry Attempts" configuration option in the Airbyte Cloud connection settings UI, allowing users to specify the maximum number of retry attempts (e.g., 1-20) before a sync job is marked as failed.

**Additional Context:**This is a basic operational control that exists in OSS deployments and would provide Cloud customers with parity and flexibility in managing their sync behavior.
